I now solved the puzzle, founded a simple way to do this thing just using an class file:
1 - Just download this file: http://www.getcodesamples.com/src/15958EA3/F43E1E1A 2 - Then add the same file to your project 3 - Add the following code:
Dim strBingKey As String = "xxxaccountkeyxxx"
Dim bingClass As New Bing.BingSearchContainer(New Uri("https://api.datamarket.azure.com/Bing/Search/"))
bingClass.Credentials = New NetworkCredential(strBingKey, strBingKey)
Dim query = bingClass.Image("Inception" + "Movie", Nothing, "en-us", "Off", Nothing, Nothing, Nothing)
Dim results = query.Execute()
For Each result In results
ListBox1.Items.Add(result.Title)
ListBox1.Items.Add(result.MediaUrl)
Console.WriteLine(result.Thumbnail) 'ThumbNail type, need to convert to use in result list
Next
Thank you all for the patience!
